Popular Examples

f(x)=(5x+20)/(x^2+2x-8)

f (x) = \frac{5 x + 20}{x ^{2} + 2 x - 8}

f(x)=-8x+x^4-6x^3+5x^2

f (x) = - 8 x + x^{4} - 6 x^{3} + 5 x^{2}

f (x) = 2^{(x - 1)}

f(k)=2k^2+22k+60

f (k) = 2 k^{2} + 22 k + 60

f(x)=x^2cos(x)-2xsin(x)-2cos(x)

f (x) = x^{2} cos (x) - 2 x sin (x) - 2 cos (x)
